Abstract

The gluon distribution f(x,k_t²,μ²), unintegrated over the transverse momentum k_t of the gluon, satisfies the angular-ordered CCFM equation which interlocks the dependence on the scale k_t with the scale μ of the probe. We show how, to leading logarithmic accuracy, the equation can be simplified to a single-scale problem. In particular we demonstrate how to determine the two-scale unintegrated distribution f(x,k_t²,μ²) from knowledge of the integrated gluon obtained from a unified scheme embodying both BFKL [log(1/x)] and DGLAP (log μ²) evolution.
